Jawbone's popular JAMBOX Bluetooth speaker is going to be getting a younger, but much larger sibling dubbed simply BIG JAMBOX soon. This information comes from a recent FCC filing (via WirelessGoodness) which doesn't seem to reveal much of anything past the new name. However, armed with this knowledge, I was able to dig up an earlier report by iLounge which caught wind of something they called JAMBOX BIG back in November. Researching further, I stumbled into upcoming product listings on Amazon for the Graphite Hex and Red Dot variants together with a number of interesting tidbits to go with them:

Can be updated with apps, software and new features via Jawbone's MyTalk portal

Up to 10 hours of power from internal rechargeable battery

As you can see, BIG JAMBOX's dimensions really do make it much larger than the original. Additionally, it's rated for 2 more hours while operating on battery power and comes with a wall power adapter which the original didn't include. Unfortunately, there are no pictures available, and all we have are the two colors (though iLounge also suggested white).

The original JAMBOX is now one of my favorite mobile accessories - it's relatively tiny, so I take it everywhere I go. Paired with my Epic 4G Touch, I have music that actually sounds quite good (especially after the recent LiveAudio update) in places I would otherwise only have a tinny speaker. Heck, I even use it daily when working in the dining room (it's become my local office for now). Clearly, BIG JAMBOX is shooting for a different, more stationary market - a perfectly understandable move on Jawbone's part.
